Electrode MP-3C 450mm 4mm (pack 3kg) Rexant 11-0952

MR-3S Rutile-cellulose electrodes 4 mm for welding carbon and low-carbon steels with a tensile strength of 480 MPa in all spatial positions using AC or DC of any polarity. Coating: rutile-cellulose, deposition rate 8.5g/A.h Electrode consumption per 1 kg of deposited metal: 1.7 kg Typical chemical composition of deposited metal: C - 0.08 %; Mn - 0.5 %; Si - 0.11 %; S - 0.025 %; P - 0.035 % Typical mechanical properties of the weld metal: Tensile strength: 480 MPa Yield strength: 370 MPa Relative elongation: 22 % Impact toughness: 130 J/cm Welds Vertical Bottom Overhead Current mode: 140-180A 160-220A 140-180A Special properties: Provides excellent quality of welded joints in installation conditions, when welding non-rotatable pipeline joints, as well as when tack welding. Allows welding of wet, rusty, and poorly cleaned metal (free from oxides and other contaminants). Electrode advantages Provides excellent quality of welded joints in installation conditions, when welding non-rotatable pipeline joints, as well as when tack welding; Easy arc striking; the weld is smooth and seamless; No pronounced transition zones between the base metal and the weld; Minimal metal spatter; Slag skin separates well from the weld; Excellent re-striking; High productivity of work; Coating does not crumble when bending electrodes by the arc; Allows welding of wet, rusty, and poorly cleaned metal (free from oxides and other contaminants); Long arc welding is permitted; Work with surfaces poorly cleaned of contaminants and oxides; Work with rusty surfaces. Advantages in welding mode: When working in AC welding mode - the arc is as stable as in DC mode; Lowest spatter percentage during welding. In this parameter, rutile electrodes approach welding in inert gas environments; Electrodes are easy to use without special training, requiring only electrode handling skills; Strong connection with high technical characteristics; Baking before welding: 140 °C for 1 hour; Welding can be performed on wet surfaces with almost no loss of weld properties; Welding of metals coated with thin layers of primer is possible; Increased slag alkalinity, which contributes to improved impact toughness of the weld; Practically no so-called hot cracks; Welds made with rutile possess high fatigue strength; Even with a short-term increase in arc length, the weld quality remains unchanged; Rutile coating reliably protects the weld from oxidation and slag inclusion.
